The correct answer is (D) diagnosis of infectious diseases.

Polymerase Chain Reaction (PCR) is a laboratory technique used to amplify or make many copies of specific DNA sequences. This allows for the detection of even tiny amounts of genetic material from pathogens.

PCR is a fundamental tool in molecular biology and is widely used in various fields, including genetic research, forensics, and particularly in the diagnosis of infectious diseases like COVID-19, HIV, influenza, and many bacterial or viral infections by detecting the presence of the pathogen’s genetic material.
